† Some links are affiliate links — they do not change the ranking
Some store links are affiliate links: if you buy through them, this site may earn a commission at no extra cost to you. It changes nothing in the ranking: the score is computed beforehand and without reading those links, and products with no affiliate programme appear exactly the same. How it is calculated.
Nothing is claimed about the formula in this category. None of these stores publishes how much active ingredient each dose carries, so the score comes from the price per capsule and the verification level, and nobody appears here as well or badly dosed: we do not have the data and we do not make it up.

- How much does a capsule of tryptophan cost?
- Between €0.058/capsule and €0.889/capsule across the 4 stores compared, with a median of €0.286/capsule. That is the price per capsule, not per pack: two tubs at the same price can cost twice as much as each other depending on what is inside.
- What certification should tryptophan have?
- Of the 30 products compared, 0 reach level 4 (the certification is backed by a third party: either we checked it with the body that issues it, or the product carries in its name a trademark that requires a third party behind it, such as Creapure or IFOS) and 0 reach level 3 (a lab report published by the brand itself). The remaining 30 stop at a certification claimed on the product page, or none at all. Only level 4 is checked against whoever issues the certification.
